My neighbor just set up a SHW thermosiphon system that seems to be working well. (AKA his showers are hot.)
It is a home made setup (under $500) and he is using the dip tube in the solar tank as the return back to the panels.
My question is: Would connecting the return (cooler water) back to the panels at the drain at the bottom of the tank be more efficient than connecting at the TOP of the tank using the deepest dip tube? His tank is above his panels.
Or.. would the effect be so minimal on the Thermosiphon that it would not be worth the effort.
Kinda scary what to white guys debate when you live in the hills. ; )
Obviously his system is working, but could we make it more efficient (sans a pump) and would it be worth it to change it over?
As always, thanks for all your great advice.
PS: All but two of my neighbors are now using SHW in some form, you gotta LOVE that!
